CAUTION
Installation and Piping
Non-explosion-proof transmitter must not be used in a place with explosive gases to prevent
serious accidents such as explosion, fire, etc.
The transmitter is heavy. Be careful when handling it.
The transmitter should be installed in a place that meets the operating conditions shown in DS
sheet or this instruction manual.
Install the transmitter according to the instruction manual. Improper installation may lead to the
cause of fall, trouble or incorrect operation.
•When installing, make sure that the transmitter interior is free from cable chips and other foreign
objects to prevent fire, trouble, or incorrect operation.
•When power is ON, do not change the position of the field indicator in an explosion-proof area.
•When power is ON, do not change the position of the transmission unit in an explosion-proof area.
•When power is ON, do not change the angle of the indicator.
•Main valve used for piping should be selected with the maximum pressure of the process taken
into account (piping parts such as main valve, etc. should be furnished by user). If the main valve
and other parts do not meet the rating, it may result in leakage of gas or liquid which could lead to
hazard.
Pressure pipes to be used must meet the temperature/pressure rating.
The cautionary descriptions listed here contain important information about safety, so they should be
observed without fail. Those safety precautions are classified into ranks “DANGER” and “CAUTION”.
Wrong handling may cause a dangerous situation, in which there is a
risk of death or heavy injury.
Wrong handling may invite a dangerous situation, in which there is a
possibility of medium-level trouble or slight injury or only physical
damage is predictable.
On items listed under “
CAUTION
”, they may also lead to serious accidents depending on circum-
stances, and must be fully observed.
The signs of prohibition and indication are explained in the following.
General items which pertain to prohibition (DO NOT)
General items which pertain to user’s action
CAUTION ON SAFETY
First of all, read this “Caution on Safety” to ensure correct operation of the
transmitter.

Wiring
On explosion-proof type transmitter, its wiring work must be performed according to the required
laws and regulations. Incorrect wiring may cause explosion, fire or other serious accidents.
Before making wiring work, be sure to turn OFF the main power to prevent electric shocks.
Use wiring materials of correct rating to prevent fire accidents.
Connect a power source of correct rating to prevent fire accidents.
The transmitter should be grounded as specified to prevent electric shocks or incorrect operation.
After installing the transmitter, firmly close the covers of the transmission unit and terminal box.
If not, rain water enter the transmitter which may result in trouble or incorrect operation.
Adjustment of Smart Type
•When using a flame-proof transmitter, do not connect HHC to the transmitter terminals and junc-
tion terminals.
Replacement of Maintenance Parts
•When removing an explosion-proof transmitter, turn OFF the main power, then disconnect the
piping and wiring. Do not remove it when the power is ON to prevent serious accident such as
explosion, fire, etc.
iv
Storage for a long period
Store the transmitter in a dry room at normal temperature and humidity.
Keep protection caps in place at the conduit connection and process connection.
For installation, select an appropriate place
Site at location with minimal vibration, dust and corrosive gas
At a place allowing an adequate space for checkup
Site at location large enough to allow maintenance and checking.
Mounting angle
Mount to a pipe horizontally or vertically.
Attention to overload
Do not apply a pressure outside the specified range.
Other
Besides the above, be sure to observe the cautions given in this manual.
The instrument nameplate as shown below is attached at the transmission unit of this transmitter. Before
use, make sure the contents of the nameplate agree exactly with your specifications.

OUTLINE
The FCX-CII series transmitter detects the differential pressure or pressure of various
fluids, converts it into a current signal of 4 to 20 mA DC and transmits it.
All the adjustment functions are incorporated in the transmission unit for making
adjustments easily and exactly.
Transmitter settings (such as range and damping time constant, etc.) can be changed from
an HHC (Hand Held Communicator).
Principle
The operating principle of the FCX-CII series transmitter is shown in the block
diagram below.
The input pressure is changed into an electrostatic capacitance in the detecting unit.
The change proportional to the pressure undergoes conditioning and amplification in
the transmission unit, and is then output as a current of 4 to 20mA DC.

(2) Check the signal wiring according to the “Terminal block connection diagram” shown in 4.1
(Page 16).
(3) Vent gas from the transmitter.
Preparation procedure
(4) Perform zero point adjustment.
When the plant requires chemical cleaning at the start of operation, be sure to
close the valve of the transmitter to prevent entry of cleaning liquid into the
pressure receiving unit.
Important
3.1 Preparation for operation
Before operating the transmitter, be sure to perform the following checks and procedures. Note
that adjustment is required in a non-hazardous area for zero point check of intrinsically safe
explosionproof and flameproof transmitters, do not open terminal cover and do not use HHC.
Use the transmitter indicator and the external adjustment screw.
(1) Check for liquid or gas leakagefrom the process
connection, etc. by applying soapy water or the
like.
5
1. After adjustment of the transmitter, it should be kept energized for about 10
seconds to write the adjustment result into memory.
2. Use a blade-edge screwdriver for adjusting the zero/span adjustment screw.
Important
Decrease
Increase
When all the checks and preparatory operations are finished, tighten the cover securely. (Tighten-
ing torque 20 N•m {2 kgf•m} <14ft-lb>)
Zero point check
Turn on the power to the transmitter.
Check the output signal of the transmitter by connecting a DC ammeter across CK+ and CK– of
the terminal block.
After ten minutes or longer, adjust the transmitter output current to 4 mA (zero adjustment). (See
below.)
(1) Zero adjustment
Zero point of the transmitter is adjustable by the zero screw on the electronics housing with
the zero adjustment screw.
If the transmitter is locked (see section
“Operating procedure”, Lock of adjustment
function), it is not possible to adjust with the
external adjustment screw.
When a digital indicator is attached to the
transmitter, make sure that the LCD lamp
“ZERO” is ON.
(2) Adjustment by HHC
Refer “zero adjustment” explained in section 7.1.

3.2 Operation
(1) Operation of pressure transmitter
Open the valve slowly to apply a pressure. When a pressure is applied, the transmitter is set
in the operating status.
(2) Operation of differential pressure transmitter
Set the operating status by manipulating the manifold valve.
Make sure the equalizing valve is open.
Open the stop valve on the high pressure side slowly.
Close the equalizing valve.

ADJUSTMENT OF SMART TYPE
To operate the FCX-CII series transmitter, the HHC is used for each adjustment.
4.1 Adjustment with HHC
Startup and usage of the Hand Held Communicator (HHC) are detailed in the instruction manual
for HHC. Please refer to this manual before commencing adjustment.
The HHC can be connected to the transmitter, junction terminal or the terminals in the instrument
room.

Important
In case of the actual scale specification with a digital indicator
provided, if the range is changed, indicator display does not match.
So, setting is required again in response to the display in the digital
indicator (G: XMTR DISPLAY). In case of the actual scale
specification with an analog indicator provided, if the range is
changed, indicator display does not match. So, replacement of the
analog indicator is required.
